Tornado winds reached 200km/h: expert

A tornado that ripped through bushland near Gerroa, leaving behind a massive trail of shattered trees, reached speeds of 200km/h, a Bureau of Meteorology expert says.

The biggest in a family of tornadoes that struck the region's south on the weekend has been given an F2 rating on the Fujita scale of tornado intensity, with F0 the least intense and F5 the most destructive.

Andrew Treloar, the bureau's manager of weather services NSW yesterday told the Mercury experts were now investigating whether the area had actually been hit by five twisters on Sunday morning.

He said three had been confirmed - at Kiama, Gerroa and Jamberoo - while it was likely Albion Park Rail and Gerringong had also been hit by separate twisters.
